The smartphone will be available from Carphone Warehouse, Phones 4U, O2 and Amazon from February 1. It will be free on contract from £25 a month and cost £380 SIM-free.

It follows the Moto G, which went on sale nationwide from mid-November, with an upgrade to the Android 4.2.2 OS rolling out from January 7.

The smartphone will come in black and white. Phones 4U has secured exclusivity on the white variant for the first three months and is giving away a wireless speaker worth £120 to anyone pre-ordering the device.

It is being unveiled at an event in London today, with representatives from manufacturer on-hand to offer a demonstration of the device.

The Moto X is powered by a dual-core 1.7GHz processor and runs the Android 4.4 KitKat operating system.

It has a 4.7-inch HD waterproof touchscreen made from toughened Gorilla glass, 10 megapixel camera with ‘Clear Pixel’ technology that it said captures the darkest scenes or stop motion blur in bright light, two-megapixel front camera, 2GB of RaM and 16GB or 32GB of internal memory.

The device also includes voice activation service Google Now, as well as the Motorola Connect extension for Google Chrome that lets users see and respond to notifications and text messages from their desktop.
